If all the facts as we know them are true...that is....the window was cut from the inside, and there was a chair under the window....then the perp PLANNED this....this was not an accidental burglary gone bad...
I can see Ricci doing an abduction in a burlgary....but I can not see him planning on just going there to take LIz....unless there was a ransom plan....
so if it was planned.....someone got in the house easily and knew he could get in....
how would a perp just wandering in the hood gather up a spare chair to put under the window...
so that leads me to think that it was someone who was already on the inside or someone who had a key ......
so let's be realistic....it could be Ricci if he had a key....but it could also have been an extended family member who had a key....it had to be someone who knew they could get in the house....
if we agree that the window was cut from the inside...and that the chair was left there....then this was a planned event...planned in advance....if it was planned in advance..someone wanted it to look like an outside person did this....
Planned in advance could be the ticket -- and someone might have staged the scenario.
